“…In fact, this variable has long been regarded, globally, as an extremely important factor in structuring estuarine fish communities, as species occurrence results from their differential tolerance to it [75,76], and for marine migrant species, namely in Tejo [21,33]. Similar results have been found by da Silva et al [77], with no seasonal effects on species composition of marine migrants, nor a correlation with environmental conditions. These authors associated these findings with the species life cycle, as they use estuaries as juveniles and remain there until they are ready for recruitment, not being affected by seasonal or environmental changes during that time.…”

Estuaries are extremely productive ecosystems, providing habitats for numerous aquatic species and crucial ecological services. The Tejo estuary, one of the largest European estuaries, has been thoroughly studied, and its important functional role as a nursery for several commercially important fish species is already established. In the present work, a trait-based approach was applied to functionally describe the fish community structure of the Tejo estuary and to enlighten potential changes in the ecosystem functioning at this level, following environmental changes expected to occur. To predict the distribution of species from the two most representative ecological guilds of the Tejo estuary, estuarine residents and marine migrants, species distribution models were built using an ensemble technique (combining forecasts of single models). The predictions obtained were more accurate for the marine migrants and the species distribution was strongly related with salinity, whereas estuarine species, were also influenced by depth, habitat type and river flow. The potential distributions of these ecological guilds showed that marine migrants will tend to use upstream areas in the estuary, where salinity is lower. Nonetheless, salinity is expected to increase as extreme weather events such as droughts tend to occur more frequently, decreasing favorable habitat availability for these species, and thus threatening the crucial role this ecosystem plays for these species.

“…It indicated essential nursing function of the surf zones, which may contribute critically to recruitment success of fish populations in the adjacent coastal habitats. We suggested that surf zone with multiple adjacent coastal habitats (e.g., mangroves, estuaries, seagrass, and coral reefs) should be set as priority of conservation (da Silva et al, 2022; Ortodossi et al, 2018).…”

“…Coastal marine biodiversity, specifically fishes, has been dramatically threatened by increasing anthropogenic activities and coastal degradation (Henderson et al, 2020; Herbeck et al, 2013). It is important to investigate the fish assemblages in coastal areas to assess their functions and to identify priority areas for conservation by comparing among multiple coastal waters (da Silva et al, 2022; Henderson et al, 2022). In this study, we investigated the daily fluctuations of fish assemblages during both neap and spring tides in the surf zones of a sandy beach at Wenchang, on the eastern coast of Hainan Island.…”

The surf zones are significantly affected by tides, however, several gaps still in knowledge of fish assemblages in surf zones response to spring‐neap and daily tidal cycles. We investigated fish assemblages in a surf zone of Gaolong Bay in China. The dynamics of fish assemblages were examined during the neap tide and the spring tide to test the hypotheses that (1) fish assemblages reflect a combination of species from around coastal habitats, and (2) dynamics of the fish assemblages were determined by both the spring‐neap cycles and diel rhythms of fish species. We collected 46 fish species comprising 16 coral reef‐seagrass species, 24 mangrove‐estuarine species, and 6 common coastal species. Fish abundance and richness were significantly higher during the neap tide than during the spring tide. Furthermore, during the neap tide, fish assemblages were mostly carnivorous coral reef‐seagrass species at night and were mostly omnivorous and planktivorous species during the daytime. However, no clear diel patterns were observed during the spring tide. We suggested that dynamics of the fish assemblages were mainly shaped by the diurnal rhythms of fish during the neap tide and by the tidal cycle during the spring tide. Our results support the notion that surveys of fish assemblages during the neap tide could collect more abundance and rich species of multiple ecotypes of fish to evaluate fish resource status in the around coastal habitats. Consequently, management approaches around surf zones with heterogeneous seascapes can lead to positive outcomes for inshore fish resources and ecosystem conservation.

“…Here, we have provided a systematic and quantitative panorama of the SESs and the threats posed to them by humans in the southwest Atlantic in Brazil. The role of Brazilian seagrass meadows has been demonstrated and quantified with respect to the maintenance of biodiversity [55,56]; habitat for fish [57][58][59][60], including important commercial species [61,62]; soil genesis; carbon sequestration; and climate mitigation [14]. Focusing on the Brazilian southwest Atlantic we do not know for certain how much seagrass we have, so it is difficult to fix a baseline in order to know how much seagrass we have probably lost.…”

The ongoing environmental crisis, driven by biodiversity loss and climate change, raises concerns about the impacts on marine systems and human well-being. These environments provide crucial ecosystem services valued at approximately USD 74.5 trillion·year−1 globally. Seagrasses support fisheries, protect coasts, help mitigate climate change, maintain biodiversity, provide food security, and enhance water quality. However, comprehensive assessments of seagrass ecosystem services (SESs) and their impacts are lacking. Focusing on the Brazilian southwest Atlantic, our aim is to bridge this gap and identify key research areas for improved management decisions. Our literature search employed n = 19 paired terms for seagrass in Brazil. We screened 30,351 search returns for 394 relevant documents. Research on SESs has grown over time, and most research has focused on provisioning and supporting ecosystem services: 79.7% of documents mentioned at least one SES, while 24.5% of the documents provided evidence of observed SESs; 31.5% only provided information on expected SESs. Provisioning services were the most observed and expected. Coastal urbanization (54%) and marine food provisioning (17%) were the main drivers impacting SESs. Terrestrial food and material provision (9%) and climate change (8%) were also significant drivers. This study provides key recommendations aimed at fostering further research and management strategies to consider the complete ensemble of ecosystem services for a range of seagrass bioregions, to better understand the provision of and impacts to seagrass services and human well-being at the global scale.
